I CONVEYER.

SPECIFICATION forming part of Letters Patent No. 758,662,A dated May 3, 1904.

conjunction with the extension bottoms of the buckets 18 to form what may be called a false bottomed compartment, so that the part of the material resting upon the forward extension as well as the main bottom of the bucket 18 may be dumped down between the pair of links 19 when the bucket is tipped by reason of the lug 20 striking the projection as before described. Each of the buckets 18 in Figure is provided with a hooked flange Q1 at its back, which takes over the axle 16a of the chain as before described.

By this means I have provided two links to each single integral bottom, whereby the chain is made much more flexible, and the bucket centrally balanced, the buckets are easily dumped automatically by the mere act of passing around the sprocket wheel 10; and they are dumped before rather than after they are carried over the sprocket wheel, as will be evident. Also the tipping up of the bucket as shown in Figure 2, will dump the whole compartment extending through two links.

In the form of bucket shown in Figure 5 I provide the sloping forward projecting edges of the bucket 18 with guard rims or flanges 15 to come in contact with the loose side links 19 so as to prevent the escape of the material between the two at the point where the side of the bucket 18 is movable with respect to the side of the compartment.

The advantage of a conveyer bucket having a rigid bottom extending through a length equal to two links of the conveyer chain will be at once evident, as it enables the bucket to dump the same amount of material as would usually be taken in two separate buckets each of which forms a link of the chain. The great advantages also to be gained by having the load in each bucket distributed on the two sides of the point of articulation whereby the dumping becomes easy, as being counter-balanced on the two side supports, will also be evident. Many other advantages of the device as shown will readily occur to those familiar with their use.

Having thus described my invention and illustrated its use, what I claim, and desire to secure by Letters Patent, is the following:

1. A conveyer bucket provided with a body and a rigid forwardly extending bottom approximately twice the length of the sides of the bucket, forming with the next preceding links a closed chamber for the purpose specified.

2. A conveyer chain consisting of alternate wide and narrow side links, combined with buckets mounted to revolve between said links and having a forwardly extending bottom from the point of articulation to co-operate with the wide sides of the chain to form a compartment therewith.

3. In a conveyer an articulated link compartment therein consisting of plain flat sides forming links of the chain and a rigid bottom of the conveyer bucket co-operating therewith to form a compartment and pivoted to the said sides at the middle of the bucket, whereby the compartment is dumped by the mere act of passing around the end supporting sprocket wheel of the chain.

4. In a conveyer the combination with aseries of links forming a chain, some of which are wide, of a conveyer bucket provided with a forwardly extending bottom reaching through the distance of two links of said chain.

5. In a conveyer the combination witha series of links, of a series of pivoted buckets having sides and one end, a forwardly extending bottom reaching to the end partition of the next preceding bucket, substantially as described.

6. A conveyer bucket provided with one end and two sides and a forwardly projecting bottom and sides therefor sloping in form and provided with guards to co-operate with the links of the chain, substantially as described.

7. In a conveyer, a bucket provided with sides shorter than the bottom thereof and pivoted about the middle of the sides so as to be dumped by tipping about the center of gravity.

8. A conveyer bucket pivoted in the conveyer chain at a point approximately above the center of the bottom of the bucket and provided with lugs for tipping the bucket about the said center.

9. In a conveyer in combination with a series of buckets having a free projecting bottom, a conveyer chain consisting of alternately wide and narrow links, substantially as described.

10. In a convey er in combination with a conveyer chain consisting of alternately wide and narrow links, a conveyer bucket provided with full height sides extending through one link, and an end partition, and a forwardly projecting rigid bottom extending between and cooperating with the wide links of the chain to form a compartment with a removable bottom, substantially as described.

11. In a convey er the combination of a series of alternately wide and narrow links, a cross shaft at the articulation of one end of the narrow links and a pair of arbors at the other end thereof, wheels on said arbors and shaft, a conveyer bucket pivoted near its center of gravity about the said arbors and having a rear end provided with a hook which co-operates with the said shaft to hold it in horizontal position, and means for tipping the buckets about the said arbors.

12. A conveyer bucket consisting of a rigid bottom, a vertical rear end, sides extending full height over half the length of the bottom and tapered toward the forward end of the bottom, said bucket being pivoted near its central point and having retaining means on its rear end to hold it in horizontal position in the links, substantially as described.I

13. In a conveyer the combination of aseries IOO IIO

of buckets having vertical sides pivoted together in alternation with plain flat side bars, each of said buckets having a forwardly projecting bottom to co-operate with said wide side bars to form compartments which are opened to dumpthe material by theviexion of the buckets about their point of articulation.

14. In a conveyer the combination with a series of pivoting shafts and arbors provided with supporting wheels, of a series of wide plain flat links connecting said arbors and shafts, and a series of conveyer buckets alternating with said Wide links each bucket hav ing a wide side through half of its length and a forwardly projecting bottom co-operating I5 In testimony whereof I have hereunder V20 signed my name in the presence of the two Isubscribed witnesses.
